On a tangential note, I ran across Dr. Hall's personal page[1] last night and learned (at least according to him) that he coined the "saltwater v. freshwater" classification in his 1976 essay.[2]

FWIW, it's refreshing to hear that eggheads can't follow Krugman. It puts me in good company!

The problem with Krugman is that he used a very "old school" Keynesian intellectual framework, while the rest of the field has moved on. The ideas of Keynes were not abandoned, but they were rendered in a form that is more consistent and coherent with neoclassical economics. Meanwhile Krugman has never been a prominent researcher in macroeconomics, but his Nobel prize and outspoken views on macroeconomics lead many people to that erroneous conclusion.

I've always wondered what would happen if we held important positions and decisions in the same regard we hold and review important economic theories, decide on climate change (IPCC panel), or choose among cryptographic hash functions (SHA competition) -- demanding each opinion be backed by a researcher well reputed in the relevant field, and overall statistical/theoretical justifications were demanded for each decision -- to try and make some provably or at least well supported significant decision in terms of optimality to reach certain clearly established goals.
